My horse came out from the pasture 2 weeks ago limping on his left front. I immediately took him to the vet, who, upon examination, found no heat, nor abnormal pulse, however there was swelling on his ankle. I put him on bute for a week and took him off of it and he was still limping. Currently I have his leg wrapped snugly as I don't quite know what else to do for him. Anyone know what might by the cause of this or any cures?
